Number of
LR Bits Check setting on pins 6 to 8 of SW1:
[ ] Bits / [ ] Units
Set the same number of LR bits
that was on the 3G2A5-LK009/
C500-LK009-V1. Make the “number of LR
bits” setting on the polling
node (node 0) in the PC
Link. The “number of LR
bits” settings on the other
nodes (polled nodes) are
ignored.
Set the same level/link
number (next item in
table) that was set on the
Unit being replaced.
The number of Units
listed in parentheses for
the 3G2A5-LK009/C500-
LK009-V1 is the maxi-
mum number of Units for
the C500 PLC. The (*1)
setting is invalid for the
C500.
(*2) These settings are
not supported by the
C500-LK009-V. If one of
these values is set, the
max. valid number of bits
will be used instead.

[
]
Pins 3 and 4: Set the same Level/
Link Number as set on the 3G2A5-
LK009/C500-LK009-V1. The CVM1-LK401’s sin-
gle-level mode is equiva-
lent to the C500-LK009-
V1’s single-level LK009
mode. The CVM1-LK401
cannot emulate the sin-
gle-level LK003 mode.
Pattern C systems do not
include Units set to sin-
gle-level LK003 mode.
